CNC cutting PE protective film is a common manufacturing process for electronic products. Below, we introduce this production process and how to select the appropriate viscosity and thickness.

1. Production process

(1) Selection of membrane material: The PE protective film typically uses polyethylene (PE) as the raw material, as polyethylene offers good toughness and wear resistance, and is easy to process and form during production.

(2) Processing of membrane materials: The production of PE protective films typically uses CNC cutting technology. First, the pattern and size of the film are designed on a computer, and then the film is cut using a cutting machine. The automatically controlled cutting machine ensures precision in the membrane material and enables efficient production.

(3) Surface treatment of the membrane: During production, the surface of the membrane needs to be treated. Common methods include coating and spraying. These techniques can protect the membrane from water, dust, and scratches, while also enhancing its glossiness.

2. How to select the viscosity and thickness combination

For standard products, the thickness is typically 0.1–0.5 mm. If higher requirements are needed, options such as 0.2 mm, 0.2–0.5 mm, 0.3 mm, or 0.3–0.5 mm can be chosen. The viscosity and thickness must be selected based on the usage environment and level of wear. When choosing the viscosity, an appropriate adhesive strength should be selected for the surface to be protected. Generally, smooth surfaces require low-viscosity films, while rough surfaces necessitate high-viscosity films. As for thickness, factors such as wear resistance and usage environment must be considered. Typically, products with significant mechanical wear require thicker films, whereas general applications may benefit from thinner protective films. It is also important to select the correct size and color according to the specific application to meet the needs of different users.

I hope this information will be helpful to you.
